The knuckle tail. 4 islflorovided with an Tliis lo'ckliftleverislooselyjmounted on a stationary aXlef'IS, which is driven horibloek 6.This bearing sn'rfaoef extends .at .gzontally inward'fthrough hole inthe lower an angle to the line'lof draft andfits thelfside'portionofthei'coupler, taking thepocorrespondingly inclined face ofthelocklfsitionshowniin Figs. 7 ,8gand9. Itis held ing blocka is also PYidd 111 0.11 (in this position hy ai'locking means, such-as the huhoftheeknuckle is prferably pro-- The lower' portion of the locking blockis a cotter pin 19, which is driven down through a'i'vertical hole inthe floor of the coupler cavity beyond the outer end of the pin whendriven home. In this way, the' extending push portion 20, which engagesthe curved rear face 21 of the knuckle tail 4, to push the knuckle openafter unlocking.

The operating lug16 of the lift lever perform s the functionsof liftingthe locking blockand of coeperating therewith to act asia-lock for thelock to prevent creeping thereby, while theleveriitself, carrying thelock, acts to throwthe knuckle open. The

' lever- 17 being loosely pivoted, any tendency of the locking block to.creep upwardly will cause'the lower shoulder 23 on the locking block toabut against the angular shoulder of the lug16 andjam' in such a way astoprevent further upward movement of the look. When, however, a liftingforce isappliedto the lever'17,--there is no jamming and the lug 16"aotsupon the upperwall of the recess 15 to liftthe lock.

. The lock-settingis performed in the following manner: The lug16 isprovided with an angular corner portion for part of its Qsurface, and astheleverl'Z is pushed upwardly, its frotation brings the angularcorinerportionof the, lug 16 intoengagement with a-shoulder 22, forming part ofthe upper wallof the recess 15, which recess is enlarged forwardly asshown inliigs. 9 and 10. This angular portion .of the lug also engages asimilar shoulder 23, in the bottom wall of the recess, thus giving thelock to the lock feature.

It will be seen that, owing to the-angular shape of the lug 16, itscoaction withthe shoulders on the top and bottomwalls of the lock recessprevents accidental upward movement of the lock and also causes theengagement which gives the lock set.- When the parts are in the normallocked position,-

- any, accidental upward movement of the locking block will cause atoggle-like action between the lowershoulder 23 and the angular shoulderof 'thelug, since the lug in its rotation willcarry the angular portionout away'from its pivot, and thus tend to jam the vertical face of thelocking block against the wall of the coupler. This same action ocoursin the lock-set position when the a'ngu lar portion engages the uppershoulder 22 afterthe locking block has been raised to the.

lock-set position. In one position ofrotation of the lever 17, the-lockwill be held in lock-set position, whilefurther rotation will causethelug 16 to ride'along the inclined face 2 1, without furtherwlifting ofthe lock, During this further rotation, the extended The lock lock liftlever upwardly.

end 20 of the lever 17 will push the knuckle open. During this openingmovement, the

lock will be held up by the engagement of the lug 16 with the inclinedtop recess wall until the tail nears.the end of its movement, when itsrising upper surface will engage and support the look by engaging theshoulder 12 thereof. The lock-set position is shown in Fig. 5, and theposition of the parts with the knuckle open in Fig. 6. When the ,liftingaction is released, the lever 20 Wlll drop from the position into whichit has been forced backwardly until the lug 16 strikes the part 15 onthe locking block.

The lever is free to take this action under gravity because the lock isat this time suspended on the upper higher face portion 10 of theknuckle tail, thus leaving the lever free to swing under gravity. Thisis an important feature, because it avoids liability of the leverstopping aftera portion of this rearward swing which might lock-set thelock. As .the knuckle tail now moves rearwardly, the lock moves downfrom the upper face 10 of the knuckle tail, the tail swings through therecess in the lock and the looking block drops down to place. It willtherefore be seen that the locking lever drops back to its normalrelation with the look before the lock has dropped to its lowestposition. The lock and the lock lift lever then both drop down to theirfinal lowermost position after the knuckle tail has passed throughtheopening in the locking block.

Any desirablejform' of bottom operating mechanism may be employed forforcing the In the form shown, there is a bottom-operating lever 25,which is pivoted between lugs 26, depending below the pivot pin hole,the hub of the lever thusealso acting as a pivot pin support in case ofbreakage. At its bend, the lever is provided with a hole or eye 27, toreceive the uncoupling lever 27, one hooked end of which is pivotallyengaged with a lug 27 on the coupler head, while the other end may beengaged by the usual lifting chain, secured to a cross rod, not shown.The upwardly curved inner portion of the operating lever abuts againstthe lower outer end portion of the lever 17, to lift this lock liftlever.

In order to 5 limit the downward movement of the operatinglever 25, Ipreferably provide it with a side projection or lip 28, which, when theparts are assembled, is above an inwardly projecting lip 29, on oneofthe hinge lugs of the lever.

; Instead of pivoting the lock lift lever loosely on an axle, a shaftmay be arranged to operate it; Thus, in Fig. 17, I have shown the shaft18 as being lengthened, with its outer portion projecting through theside of the coupler head, and having an opcrating arm 30, which maybeconneeted by a chain 31, to the uncoupling lever or'may be otherwiseoperated- In this case, the intermediate portion of the shaft is securedto the lever 17 by a spline connection 32, and the outer portion of theshaft which is preferably enlarged may beprovided with a groove 33,engaged on one side by a cotter or pin extending through averticalholeinside the coupler. prevent endwise movement of the shaft, whileallowing its rotation. In this case, the rotation of the shaft willswing the operating lever 17, the action being the same as before.Instead of allowing the operating lever to merely abut against the locklift le ver, I may provide them with a pivotal link connection 34:, asshown in Fig. 18.

The advantages of ,my invention result from relieving the pivot pin froma great part of the strain thereon, without departing from the usual M.C. B. lines. Also from the simple and effective lock and lockoperatingmechanism, which provides for locking the lock, lock-lifting,lock-setting, and knuckle-throwing.

Many variations may be made in the form and arrangement of the partswithout departing from my invention.
